Review on HEMUNC 5pcs Mixed Universal Carbide Oscillating Tool Blades Set - Quick Release Saw Blades Accessories Kit for Tile Grout, Mortar, Concrete, and Masonry by Ken Cudal

These blades have exceeded my expectations as I remove a thin layer of Duraroc grout in small sections. In my opinion I use these outside of their design and I still use the first one and it still cuts just as well as it did straight out of the box. I use an oscillating saw because my 7" diamond cup creates a dust storm even with an industrial vacuum/dust collector attached, luckily I only have small areas to sand. I wish there was a larger version of this saw/blade, it's slow and dust free.
